Communication module I 24 sends it to cpu I 23, and the threshold value received is stored in built-in ROM by cpu I 23.In addition, thresholding
Value can also be write direct in its cpu I 23 when wisdom terminal box 2 is dispatched from the factory and be stored.
1, local control：
1.3, parameter information acquires：
The acquisition module 21 of wisdom terminal box 2 is periodically (such as：5 minutes) acquisition photovoltaic module 1 running parameter, that is,
The electric current I of photovoltaic module 11, voltage V1And 3 diode current ID1、ID2、ID3Or voltage VD1、VD2、VD3And wisdom terminal box

1.2, breakdown judge：
Cpu I 23 is by parameter information that acquisition module 21 is transmitted and the door that is stored in ROM built in cpu I 23 in step 1.1
Limit value carries out operation comparison and breakdown judge；
As the electric current I of the photovoltaic module 1 acquired1, voltage V1Or 2 internal temperature T of wisdom terminal box1Persistently exceed thresholding
Value a period of time (such as half an hour) then proves that corresponding photovoltaic module 1 exists and blocks or failure；The present invention can also be on this basis
Operation comparison is carried out by the threshold value to 3 diode current/voltage, to judge that the photovoltaic module 1 is that whole damage is gone back
It is partial destruction, the specific method is as follows：
Method one：Current method breakdown judge：Consider that sampling error, the threshold value of 3 diode currents may be provided at 0.01
0.1A is set as within the scope of~1A, in the present embodiment, and (electric current is that positive direction indicates that electric current flows to the negative of diode by diode cathode
Pole).
Electric current ID1When higher than threshold value, judges that the silicon wafer board group of diode D1 parallel connections exists and block or failure.
Electric current ID2When higher than threshold value, judges that the silicon wafer board group of diode D2 parallel connections exists and block or failure.
Electric current ID3When higher than threshold value, judges that the silicon wafer board group of diode D3 parallel connections exists and block or failure.
As the electric current I of three diodesD1、ID2And ID3When being above threshold value, judges that photovoltaic module 1 is whole and block
Or failure.
It judges that principle is as follows：
It is blocked or when failure when silicon wafer board group exists, the diode current flow in parallel with the silicon wafer board group, at this time in diode
Electric current passes through；When silicon wafer board group works normally, diode cut-off, by diode current close to 0.Therefore by setting diode
The corresponding threshold value of electric current can effectively detect corresponding silicon wafer board group working condition.
Method two：Voltage method breakdown judge：Consider sampling error, the threshold value of 3 diode voltages may be provided in -0.01
- 0.05V is set as in~-0.1V ranges, in the present embodiment, and (positive direction of voltage is：The cathode of diode is directed toward anode).
Voltage VD1When less than threshold value, judges that the silicon wafer board group of diode D1 parallel connections exists and block or failure.
Voltage VD2When less than threshold value, judges that the silicon wafer board group of diode D2 parallel connections exists and block or failure.
Voltage VD3When less than threshold value, judges that the silicon wafer board group of diode D3 parallel connections exists and block or failure.
As the voltage V of three diodesD1、VD2And VD3When being below threshold value, judges that photovoltaic module 1 is whole and block
Or failure.
It judges that principle is as follows：
It is blocked or when failure when silicon wafer board group exists, the diode current flow in parallel with the silicon wafer board group, at this time diode two
The voltage at end is opposite with defined voltage direction, that is, voltage is negative；When silicon wafer board group works normally, diode cut-off, diode
The voltage at both ends is corresponding silicon wafer board group voltage, that is, voltage is just.Therefore by setting the corresponding threshold value energy of diode voltage
Enough corresponding silicon wafer board group working conditions of effective detection.
Note：It can be needed to select suitable voltage threshold or current threshold according to real work.In practical work process
Diode-number is not fixed, but consistent with the above method to the method for its breakdown judge.
Bypass Control is carried out when 1.2.1, breaking down：
When the result that operation compares judges that photovoltaic module 1 occurs blocking or failure, and continue for some time afterwards (such as：1 is small
When), then cpu I 23 (or entirely breaks down to the part failure electricity-generating circuit of photovoltaic module 1 by control module 22
Photovoltaic module 1) Bypass Control is carried out, avoiding the occurrence of the photovoltaic module 1 of failure influences the hair of photovoltaic module 1 of other normal works
Electricity promotes generating efficiency.In the present embodiment, each diode switch in parallel with what control module 22 was connected (that is, open
Close F1, switch F2 and switch F3), normal condition lower switch disconnects, and switch when bypass is needed to be closed.When switch is closed, diode
And its corresponding silicon wafer board group is bypassed.
Meanwhile after the completion of above-mentioned Bypass Control, the cpu I 23 of wisdom terminal box 2 is by event information through communication module I 24

According to event is bypass at this time.
Note：Judging result, which is that photovoltaic module 1 is whole, to be occurred blocking or when failure, can be in conjunction with operating condition at that time (such as day
Gas) judge that the photovoltaic module 1 does not damage failure, but the faint unsuitable photovoltaic module 1 of intensity of illumination works, and is not necessarily to work at this time
Personnel go to repair, it is only necessary to bypass recovery is controlled when operating condition meets.
1.2.2, recovery control is carried out after the completion of the fault restoration of step 1.2.1：
After the photovoltaic module 1 of failure is repaired, the data that I 23 pairs of acquisition modules of cpu are acquired at this time are according to step 1.2
Recovery processing is carried out after re-starting operation comparison and breakdown judge, cpu I 23 is terminated by control module 22 to photovoltaic after reparation
The Bypass Control of component 1 restores the normal power generation work of photovoltaic module 1, and event information (event is to restore at this time) is reported
To monitoring central platform 4.
The above-mentioned judgement principle to photovoltaic module after reparation 1 is as follows：
Current method：When being connected in parallel on the switch closure at diode both ends (that is, bypass), the electric current detected at this time is by two
Pole pipe and the total current for being connected in parallel on its two end switch, that is, pass through the electric current of diode-switch in parallel circuit：When silicon wafer board group is deposited
When blocking or failure, electric current is flowed out by switching, that is, is switched while being bypassed corresponding silicon wafer board group and diode, opens at this time
Pass has electric current to pass through；Work as Failure elimination, when silicon wafer board group can work normally, silicon wafer board group starts to generate electricity, at this time the silicon crystal slate
A reverse current is will produce between group and switch, with the upper original positive and negative counteracting of electric current of switch, passes through diode-switch in parallel
The electric current of circuit, to judge the silicon wafer board group Failure elimination, can carry out recovery processing close to 0 or less than 0.
Voltage method：When being connected in parallel on the switch closure at diode both ends (that is, bypass)：Cpu I 23 need to be 22 weeks by control module
The control of phase property disconnects inductive switch (that is, closure switch), and the voltage of diode not bypassed to make acquisition module 21 acquire is right
Voltage value judges, if voltage is just, that is, indicates silicon wafer board group Failure elimination, gets out of the way shutdown at this time and open (that is, recovery processing),
Voltage is 0 or negative value, that is, indicates that silicon wafer board group failure is not eliminated, continues to get out of the way closing conjunction (that is, keeping bypass) at this time.
